No it hasn't. Please stop saying this. If you read their actual financial filings instead of press releases, it is very clear that they are not profitable on a GAAP basis without accounting games in any region, especially this year. They hide their unprofitability with non-GAAP figures and loss allocation to departments where they don't really belong (ex. technology development).
If you knew anything about accounting you would understand that what you’re saying is preposterous. Hiding by allocating their losses to the technology department? If you have proof of this please bring it up because what you’re saying is blatantly illegal and the CEO, CFO etc will all be liable. Otherwise if you’re just speculating then say so.
As to GAAP you don’t understand what that term is because that’s more about having a standard way of representing numbers but GAAP numbers don’t show the true numbers because of many different accounting rules like accounting for employee stock, which does not hit cash flow.
